DUSTLESS STREET Application filed Iune HO,

This inventionrelates to new and useful improvements in a dustless and disease preventing, garbage collecting and street cleaning machine.

5i The invention has for its object to construct a dustless street cleaning and garbage collecting apparatus which safeguards the operator from contracting any lung disease by breathing dust and makes garbage col lecting easy. inexpensive and safe.

As a further object of this invention it is proposed to provide a means whereby the container carriage may assume a position upon ground and adapted to be hoisted up over the top of said container body and discharge into the container.

As a further object of this invention it is proposed to associate the means mentioned in the previous paragraph with one of the wheels of a chassis equipped with the container body in a manner so that the vehicle may be moved to cause motion of the container carriage.

As a still further object of this invention it is proposed to connect the extension members from the partial cover in a manner so as to automatically extend as the container carriage is hoisted thereover from therear to the front.

For further comprehension of the invention, and of the objects and advantages there of, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure Fig. 1 is a side elevational view of a device constructed according to this invention.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a rear elevational view looking in the direction of the line 33 of Fig. 1.

Fig. 4 is a fragmentary view similar to a portion of Fig. 2 but illustrating the device in another position.

CLEANING TRUCK 1932. Serial N0. 620,058.

Fig. 7 is a'perspective view of the container carriage per s'e.

The street cleanin' machine according to this invention comprises a container body 10 havin' an open top 11. A partial cover 12 cxten s over the rear portion of the container body and is inclined from the bottom upwards towards the front. This partial cover is slightly curved as plainly shown on the drawing. A plurality of telescopic leaves 13, w 14 are connected upon under side of the partial cover 12 and arranged so as to be capable of extending in telescopic manner. The leaf 13 is shown formed with elongated slots 15 extended substantially from the front to the rear and rivets 16 are fixedly mounted upon the partial cover 12 and the telescopic element 14 and engaged through the elongated slots 15 so as to telescopically hold the parts together. In Fig. 1 the leaves are shown rem tracted while in Figs. 4 and 5 they are extended.

A container carriage 17 is adapted to engage over the partial cover 12. In Fig. 1 this container carriage is shown in full lines in an intermediate position and in dot lines 18 in a lowered position resting upon the ground, and in dot line 19 in the fully extending position discharging into the container. The carriage 17 comprises a pair of vertical side Walls 20 and a bottom 21. door strip 22 is hinged upon one end of the bottom 21 and another door strip 23 upon the other end. This door strip may be opened flat or may be pivoted and held tightly 35 against the edges of the walls 20. Catches 24 serve to hold the door strips 22 and 23 in their closed positions.

A 'rod 25 is attached upon the contamer carriage 17 and extends slightly to the front of it. This rod 25 is adapted to engage hook elements 26 formed upon the free end of the leaf 14. The arrangement is such that when the carriage is moved upwards over the partial cover 12 the rod 25 will automatically engage the hooks 26 and thus connect with the leaf 14. Further motion of the container carriage will then cause the leaves to be extended.

A means is also provided whereby the container carriage 17 may be hoisted over the top of the container body. This means comprises cables 28 attached upon the sides of the container carriage l7 and extended over a roller 29 rotatively mounted in the body 10. Each of the cables 28 has several turns over the roller. One of the cables, the cable on the left as shown in Fig. 3 has its end permanently attached upon the roller 29. The other cable 28 has its end extended downwards and connected upon a hook 30 coaxially on one of the wheels 31 of the body 10. This wheel is equipped with a drum 32 provided with a lateral opening 33 through which the cable passes. The arrangement is such that the vehicle may move to cause a cable to wind upon the drum 32.

The body 10 may be mounted on the chassis of a motor vehicle or may be attached upon a puller and act as a trailer. A rope 34 is attached upon the container carriage 17 by which the carriage may be drawn back to its position upon the ground. Other ropes 35 are attached upon the leaf 11 so that the tclescopic leaves may be drawn back to their retracted positions. A pawl 36 is supported upon the body 10 and engages teeth 37 upon the drum 29 so that the container carriage 17 may be held in any lifted position. A removable cover 40 is adapted for closing the top of the container body when refuse is not being loaded into the container body.

In operation the container carriage should be placed in position shown in Fig. 1 by the dot and dash line 18. Then refuse and-other matter filled therein. To move the container carriage over the container body, the cable 28 should be connected with the hook 30 and then the vehicle slightly moved to cause the cable 28 to be pulled and so lift the container carriage over upon the partially closed back 12. Whenever desired the container carriage 17 could be tilted for dumping into the container body 10. If the cable 28 is pulled sufiiciently the container carriage 17 will cause the extension of the leaves, 13, 14, and so it is possible that the contents of the container carriage may be emptied into different portions of the body 10. It is to be understood that my street cleanmg apparatus may be of any suitable size and material and the cover may be removable or folded on the truck in any suitable manner.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. A street cleaning machine, comprising a. container body opened at the top, a partial cover on the rear end extending at an inclination from the bottom to the top, telescopic leaves on said partial cover adapted to be extended, a container carriage for being hoisted along on said partial cover and telescopic leaves, means on said container carriage for gripping and causing the extension of said telescopic leaves, and means for lifting said container carriage over said partial cover said means for gripping comprising a rod attached upon and extending from the front of said container and adapted to engage a hook element on the last of said telescopic leaves.

2. A street cleaning machine, comprising a container body opened at the top, a partial cover on the rear end extending at an inclination from the bottom to the top, telescopic leaves on said partial cover adapted to be extended, a container carriage for being hoisted along on said partial cover and telescopic leaves, means on said container carriage for gripping and causing the extension of said telescopic leaves, and means for lifting said container carriage over said partial cover, said telescopic leaves including elongated slots on certain of the leaves, and rivets on other of the leaves engaging said slots.

3. A street cleaning machine, comprising a container body opened at the top, a partial cover on the rear end extending at an inclination from the bottom to the top, telescopic leaves on said partial cover adapted to be extended, a container carriage for being hoisted along on said partial cover and telescopic leaves, means on said container carriage or gripping and causing the extcnsionof sa d telescopic leaves, and means'for lifting sald container carriage over said partial cover, said means for grippingcomprlsmg a rod attached upon said container and adapted to engage hook elements on the last of said telescopic leaves.

In testimony whereof I have aflixed my signature.

LOUIS SIMON.
